Understanding Cancer -- Symptoms
What Are the Symptoms of Cancer?
In its early stages, cancer may have no symptoms, but eventually a malignant tumor will grow large enough to be detected.
As it continues to grow, it may press on nerves and produce pain, penetrate blood vessels and cause bleeding, or interfere with the function of a body organ or system.
The Seven Warning Signs of Cancer

- Sore that doesn't heal

- Are on the list of signs of cancer
- Aren't related to another cause
- Last for more than two weeks
